I hope this move changes the hostile amount of google services that are baked into Chrome and Chromium. Not saying MS is any better, but at least there will be more choices for users and where before everything was hardcoded, now there will be an option to select and potentially expose more customization for us morals.
There are several services and binaries. Some examples are Google host detector, Google URL tracker, Google cloud messaging, Google hotwording, Safe browsing, password saving feature naggs you to sign-in, translation etc. There are also a lot of binaries that are bundled, but im not really an expert on those.
The store comes to mind, but see, for example, the inox patchset[1], part of ungoogled-chromium[2], which tries to minimize what Chromium calls home for (e.g. a bunch of extensions, Google accounts, and a few services which sync data with/ping the Google servers).
